Tirukkural 421: Fortress of Wisdom

Wisdom is a weapon to ward off destruction; it is an inner fortress which enemies cannot destroy.

Image of Satguru Sivaya Subramuniyaswami
Because Self Realization must be experienced in a physical body, the soul cycles back again and again into flesh to dance with Siva, live with Siva and ultimately merge with Siva in undifferentiated oneness. Yea, jiva is actually Siva.
—Gurudeva
